Hi, I've with sucess connect moppy with floppy drives (and play midi) but now I'm trying to play midi on NEMA stepper motors. I connect A4988 driver with stepper motor but this not work, motor didn't spin only play very very low noise. What should I do to play midi on NEMA motor with A4988? Should I make some changes on arduino program code? Can anybody show me scheme how to connect moppy with arduino and A4988?
